Kotori Works' kids' thick-soled pile socks. They were very warm, and my child wore them repeatedly, so the heels and toes are thin and there is some pilling, but there are no holes. They show considerable signs of use, but since they haven't been re-released in recent years, I'd like to offer them to anyone who wants to try them. Due to shipping location, I may change the shipping method from Yu-Yu Mercari Bin to Raku-Raku Mercari Bin. Applicable size: 16-18cm Color: Mocha Brown Material: 87% wool, 12% nylon, 1% polyurethane Production: Made in Japan (spinning, dyeing, and knitting are all done in western Japan.)
